It can be a good idea to enable appkeys in budgie. This means open an app from the icon task list at the panel through Super+numkey
For eg, Super + 1 will open the first app, Super + 2 will open the 2nd and so on.
This kind of functionality was available in unity and can be enabled in gnome using appkeys extension, dash to panel etc.
This functionality increased the productivity, by a great time allowing to switch between apps very easily.

Is there a support for something like this?
Can something like this be implemented by making a new applet?
